CAB OR DECK SEAT.

Application filed Becember 30, 1927.

'lhe present invention relates to a seat for use on locomotive cabs,tractors, reapers, binders, and sundry other motive engines orn'iachines and has for its prime object to eliminate and overcome theridges, jolting inet-ion particularly resultant frein the lateral swingor side swing of the engine or machine in niotion, just perinitting theoperator to retain his proper position.

Another very important object of the invention resides in the provisionof seat structure of this ynature which provides necessary adjustmentsoas to position the seat for the convenience of diiferent operators usingthe saine.

Another very important object of the in vention resides in the provisionof a seat which is free to swing upon a pivot, laterally or sidewise, insuch a way to counteract and eliminate the lateral motion of the inovingobject en the machine, the swing of the seat being regulated by springmeans located reniote from the pivot.

Another very important object of the invention resides :in the provisionof a seat structure of this nature which is simple and easy in itsadjustment, being capable of adjnstn'ient at its base forwardly orrearwardly and. the height of the seat being adjustable.

fnotl'vr very important object of the invention resides in the`provision of a strncture of this nature wherein the parts are capableof easy and quick asflsenibly and disassembly.

it still further very important object of n 1 ab he invention resides inthe provision of a l seatstructure of tris nature which is strong anddurable, coinpact and convenient, in-

expensiveto manufacture, thoroughly eiii-- cient and reliable in use andoperation, and otherwise well adapted to the purpose for which it isdesigned. n

lilith the above and numerous other Yiew as will appear as the descrip#n proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter niore fully described and claimed.

ln the drawing: L

Figure l is a side elevation of` the seat structure embodying thefeatures of iny invention,

Figure 2 is a front elevation thereof,v4

Serial No. 241,321.

Figure 3 is a rea-r elevation of the upper portion thereof,

Figure 4 is a transverse horizontal section talren substantially on theline 4 4 of Fignre l,

Figure 5 is a horizontal transverse section taken substantially on theline 5 5 of Figure l, and

Figure G is a transverse section taken substantially on the line 6-*6 ofFigure l.

Referring to the drawing in detail, it will be seen that the letter Bdenotes a base which is of U-shaped 'formation to comprise a bottom side5 merging at one end into a bight 6 rising therefrom and merging into anupper side Y extending over the bottoni side 5 and terminating in adepending leg 8; lThe bottoni side 5 is provided with transverse slots 9through which inay be eX- tended screws, bolts or other suitablefastening elements 10 to secure the base to the iioor or other support,said slots permitting transverse adjustment of theA base as may bedesired frein time to time. rlhc upper side 7 is provided with anelongated longitudinally extending slot 11 which partially extends intothe upper portion of the leg 8 to forni a relatively wioe entrance l2.

The letter S denotes a standard which rises from the baseB. Thisstandard S is yoifset intermediate its ends as at 13 so that the upperportion of the standard is located. forwardly of the Vlower portionthereof. rlhe bottom end of the standard S has a forwardly directedextension 14. Bolts 15 extend through the extension 14 and through theslot ll in order that the standard may be securedito the base and may beadjusted longitudinally thereof. The upper ond ofthe standard isprovided with upwardly directed and laterally offset eXtensions i6 whichterminate at their upper ends in bearings 17 `hat are alined to receivepin 18 having a pair of springs 19 thereon.

' rl`he letter l? denotes pendnlnin which is in the forni of a straightbar the lower end being formed with a series of longitudi nally spacedopenings 20. rihe intermediate portion of the pendulum P is providedadjacent the upper portion thereof with an opening 0 the lower portionof which is comparatively enlarged as is indicated at 2l while the upperportion thereof'is comparatively sinall as indicated at 22. A pivot bolt23 projects from the intermediate portion of the upper part ot thestz'ndard S andy the head of this pivot bolt is su'llieiently small topass through the portion 2l of the opening O so that the shank of thebolt may be received in the relatively small portion 22. Thus thependulum may be easily and quickly assembled and disassembled in respectto the standard S when desired and yet is prevented from accidentaldisassembly therefrom. The upper end of the pendulum P has one cornerthereof bent rearwardly to provide an extension c enoted specilically bythe numera` and apertured to receive the pin 18. This extension 25 isdisposed between the springs 1S) and these springs are so tensionei'l asto impinge against the bearing i7 and against the eX- tension` 25 tonormally hold the extension 25 centrally on the pin i8 that (is tonormally hold the pendulum in vert., position. The opening in the eiteiis i ndieated in dotted lines in Figure 3 numeral 2G is sufficientbv andit is noted that this opening ly large to accommodate the arcuatemovement of this extension 25 in espect to the axis formed by the pivotbolt 23. One of the bearings 17 has a detachable cap 17 normally held inplace by bolts 28 so that this cap may be removed for the readyasseinbly and disassembly of the pin lo in re spect to said bearing 17.

he letter A denotes generally a seat bracket which is of lil-shapedformation to comprise bottom relatively long` arm 29 merging at one endinto an upwardly extending curved bight 30 which in turn merges into anupper relatively short arm 3l. These arms 9 and 8l are provided withregistering openings to recei a shank 32 of a seat 83, the shankdepending` from the and having a spring Sal therealiout resting on thearm 3l and abutting the bottom of the seat or au enlargement on theshank. The other end of the arm 29 merges into a pin or finger adaptedto extend into one of the openings 2O depending upon the de- .siredheight of the seat from the floor or other support. A clamp structure Cengages the b 'acket A on the bottom end of the pendulum and comprises apair of side plates 36 having curved jaws 37 at their rear edges toreceive the side edges of the lower portion of the pendulum P. A. holt38 extends through the pla-les 36 and through a sleeve 39 formed on theextremity of the upper arm 3l. A clamping bolt all extends through theplates 36 and may he tightened for clamping the jaws of the plates intight frictional engagement with the side edges of the pendulum l.Bottom edges of the plates 36 have inwardly directed lingers 4l to reston top of the lower arm 29 as is clearly indicated in Figure 2.Obviously the bolt l() may be unloosened so that the bracket A may berocked on the bolt 38 to withdraw the ,linger from the opening 2O inwhich it is situated so that the bracket may be raised or lowered andthe linger inserted in another one of the openings 2O so as to disposethe seat at the desired height and then, of course, the bolt 40 will betightened to securely and frictionally clamp the jaws 3T against theside edges of the pendulum.

. rIhe seat 33 may be made of metal or wood, dressed or out, to form anordinary seat with or without a bark and may be cushioned if desired.rlhe shank 32 which extends through the openings T is square so as toprevent turning of the post in resiliect to the bracket A. lpre''eral'ily provide two or more of the openings i7 in each arm 2l), 3lso that the seat may he adjusted forwa rdly or rearwardly as may bedesired in respect to the pendulum l). In order to prevent accidentaldisplacement of the shank 32 it is preferable to provide a cotter pinafi or the like extending therethrough for engaging the bottoni surfaceof the lower arm 29 From the above detailed description it will be seenthat I have provided a floating and frame or `bracket structure of aflexible and shock absorbing nature becausel of the resiliency of thebracket A, the standard S and the base B. This seat structure willeliminate or reduce to a minimum the lateral or side swing and absorbshocks incidental to the motion or sway of moving locomotive or otherfeatures of mechanism operated on tracks, highways or the earth surface,said seat floating or swinging on a pendulum dial hanger or support vitha de vice adjusting and regulating its motion. ll will also be seen thatl1 provide au anti-friction roller 5() having an axle 51 disposedvertically and journaled in bearings 52. This anti-friction roller 5()projects througl an opening` in the standard. S below the pivot bolt 23so that the pendulum l? may engage therewith thus reducing friction to aminimum and elin'iinating the tendency of the pendulum to flex too muchlongitudinally of the motion of the machine or mechanism in which thisstructure may be mounted.

This structure is easily adjustable in its position forwardly,backwardly or to either side and is adjustable as to its height. It willalso be seen that all parts of the. apparatus are capable of beingreadily reunoved 'and replaced.

The result of these novel features of construction is the comfort andhealth of the person using the same.
